74FCT807CTPYG8

Overview

The 74FCT807CTPYG8 is a clock driver and distribution component manufactured by Renesas Electronics Corporation. It functions as a 1:10 clock buffer with TTL outputs, designed for high-speed signal distribution. The device operates within a supply voltage range of 4.75V to 5.25V and supports a maximum frequency of 100 MHz. It is housed in a 20-SSOP package (0.209 inch width) and is rated for commercial operating temperatures between 0°C and 70°C. This integrated circuit belongs to the 74FCT series, providing fan-out buffering capabilities for digital systems.

Feature Summary

• 1:10 Clock Driver with TTL Outputs
• Maximum Frequency of 100 MHz
• Supply Voltage Range: 4.75V to 5.25V
• 20-SSOP Surface Mount Package

Applications

• Clock distribution networks
• Digital system timing synchronization
• Bus-oriented applications requiring signal buffering

Procurement Notes

Verify component status prior to procurement as the 74FCT807CTPYG8 is listed as obsolete or end-of-life by major distributors. Confirm availability through authorized channels or secondary markets. Ensure that the specific suffix 'CTPYG8' corresponds to the required temperature grade and packaging format, as variations exist within the 74FCT807 family. Cross-reference datasheets for pin compatibility if substituting with other packages like QSOP or SOIC.

Selection Notes

Select this component when a single-ended input requires expansion into ten TTL-compatible clock outputs. Verify that the system operates within the specified 0°C to 70°C temperature range and utilizes a 5V logic supply. Consider alternative packages such as 74FCT807CTQG8 for QSOP requirements or 74FCT807BTPYGI8 for different speed grades if the SSOP form factor is unsuitable for the target PCB layout.

Part Context

This part belongs to the Renesas 74FCT807T series of fast CMOS TTL-compatible logic devices. It serves as a fan-out buffer, distinct from latches or multiplexers within the same product line. The 'CT' designation typically indicates a commercial temperature grade, while 'PYG8' specifies the SSOP package and reel/cut-tape packaging configuration.

Replacement Considerations

Publicly confirmed substitute part numbers include IDT74FCT807CTQG8 and IDT74FCT807BT/CT. Check for equivalent functionality in the 74FCT3807 series for LVCMOS inputs if voltage levels differ.
